Ruger P94DC question

I recently purchased a Ruger 40 cal P94DC that came with one magazine. I would like to purchase additional mags, but can't seem to find them (but I can find P944 mags). Does anybody know if the Ruger P944 mags are interchangeable with the P94? Any help would be greatly appreciated.

If you go to Ruger website and look for the "contact" link you can email your question and they usually answer promptly. I've used it a half dozen or so times and always received an answer or resolution to my question or problem. Good luck.
